The safety and tolerability of hLF 1-11 has to be established first in HSCT recipients who are at risk of developing, but have not yet developed, infectious complications due to invasive fungal disease. These patients are different from healthy volunteers because they have received myeloablative treatment which not only arrests haematopoiesis resulting in neutropenia but also induces mucosal barrier injury both of which predispose to infections which typically occur during the week after transplant. It is therefore essential to know that hLF 1-11 is when given during neutropenia and mucosal barrier injury before infections ensue

Background:
Human lactoferrin (hLF) is a glycoprotein containing 692 amino acids and found in the saliva, milk, tears, and other body fluids. Peptide representing the first cationic domain, i.e. a peptide comprising the first eleven residues of hLF (further referred to as hLF1-11) was significantly more effective than the full length hLF or the peptide representing the second cationic domain in killing a variety of bacteria in vivo. The mechanism of action comprises a number of independent factors. The classical way to explain the efficacy is the direct killing effect, which typically is observed in vitro at relatively high concentrations. The results of in vitro and in vivo experiments suggest that the mechanism of action is predominantly through the intermediary of cells and/or components of the host as opposed to a direct interaction with the pathogen.
The objective is to develop hLF1-11 as an effective and safe antibacterial and antifungal for the treatment of fungal and bacterial infections that develop during the neutropenia that results from myeloablative therapy to prepare for a haematopoietic stem cell transplant (HSCT) formerly referred to as bone marrow transplant. Rates of infection and related morbidity are high in this population making it an attractive target for testing clinically the proof-of-principle that hLF1-11 can provided effective treatment. Subsequently, hLF1-11 will be developed further as a systemic antifungal agent.
